The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...
to evaluate the effect of drought stress, biofertilizer and chemical phosphorus fertilizer on yield and seed protein percentage of two lentil cultivars, an experiment was conducted in split factorial based on crbd design with 4 replications in research farm of university of tehran (karaj-iran) during 2009-10. the main factor including three irrigation levels (irrigation after 70, 90 and 130 mm ...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...

Biosolids are utilized as nutrient rich fertilizer. Little material is available on benefits to forage crops resulting from fertilization with biosolids. This paper aimed to compare the effects of fertilization with biosolids versus commercial nitrogen fertilizer on growth, root formation, and nutrient value of triticale plants in a greenhouse experiment. Per treatment, five pots were seeded wi...
effect of saline water and nitrogen application management at different growth stages on wheat yield
nitrogen is the primary nutrient that shows deficiency in saline areas, therefore, proper nitrogen fertilizer management is one of the strategies to achieve higher wheat grain yield. a field experiments in a saline soil was performed on wheat with a factorial arrangement in randomized complete block design with four replications, in rostagh area, 25 km from yazd. the first factor was nitrogen ...
Increased interests in low-input agriculture in recent years has seen the growing developmentin the use of commercial biological inoculants to increase the mobilization of key nutrients suchas nitrogen (N), phosphorus (P) and potassium (K) to enhance their availability to crop plants.The objectives of this field experiment with tobacco were to determine i) reduced rates ofinorganic fertilizer c...
in order to investigate the effect of different levels of biofertilizer inoculation and phosphorus chemical fertilizer on mineral elements absorption in forage corn sc. 540 under humidity regimes, an experiment was conducted as line source based on a randomized completele block design with three replications during two growing seasons of 2012 and 2013. the implementation of line source was appl...
